TANK.

Application led April 26, 1922. `Serial No. 556,569.

To all 'whom/t may concern: I

Be it known that I, ANDREW A. KRAMER, a citizen of the United States, residing at Kansas City, in the county of Jacksonand State of' Missouri, have invented certain new and useful Improvements .in Tanks; and I do declare the following to be a full, clear, and exact description of the invention, Such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to thev accompany'- ing drawings, and to the figures of reference marked thereon, which' form apart of'- this specification. This invention relates to tanks and particularly to tanks of relatively large capacities.

The invention is particularly adapted for use in connection with large oil tanks where the roof areais considerable, the roofs of such tanks having a tendencyto sag and it b the interior supporting means for is a more or less engineering problem to build a tank of sheet metal and properly support-the roof.

My invention contemplates the provision 'of means whereby the essential parts of the tank 'can be constructed or fabricated in the factory and sent out into the fields where they may be conveniently erected to provide a tank of considerable area.

The particularly novel features of the in; vention will be apparent by reference to the following description in connection with the accompanying drawings, in which- .Fig 1 1s a view partly in elevation and.

partly in section, showing a tank constructed in accordance with -my invention, the roof being shown in elevation.

Fig. 2 is an enlargedfragmentary view of the prop, part. of the roof being. shown in section.

Fig. 3 is a cross sectional view on the line 3--3 of Fig.- 2. A

Fig.l 4 is a fragmentary detail view of one of the struts constituting the top, and the.

tie rod therefor.

Fig. 5 is a sectional view through a4 slightly modified form of strut tie and girder brace, and

Fig. 6 is a further modified form of the girder brace and strut tie plate.

Referring now to the drawings by numerals of reference: v

1 designates the vertical' wall of a tank plate having at its upper end an outwardly errof the roof may be supported. The center of the roof is adapted to be supported by a prop. The prop l1s shown as comprising a centrally located standard or pipe 3, having at its upper end a central roof sheet comprising a conical disk 4, the convex portion of which is uppermost and the disk is provided at its edge with a depending bracing flange 5.

- Below the disk or roof sheet 4 is welded ,a sleeve 6, having an outwardlyextending flange 7 and between it and the roof sheet 4" is another sheet 8.` The flanges/on the two sheets may be fastened together if'de1 sired, the roof sheet 4 having a central opening through which the upper end of the standard or pipe'3 projects.

The roof sheet 4 1s reinforced by a supporting cone 9, which is inverted withrespect to the roof sheet 4 and which has a tending flange 2, upon which the outer edge I pipe of suitable diameter, carries a step or platform 13 at its lower end vand slidable on the standard 3 is a sleeve 14, to which may be welded a plurality of upwardly disposed, radial struts or braces 15, and the braces preferably consist of two parts, the lower member of each of which is hollow to receive the rod 16, constituting the upper half of the brace. They upper half of each brace is fastened to depending tie plates, which also constitute reinforcements for the roof, as will bepresently explained.

Welded to the core. 9 and extending downvwardly therefrom are tie rods 17, which'are received in the sleeves 18, integral with the lowen' members of the struts, as seen in Fig. 4. The lower ends of the upper members 16 of the struts may be fastened to the upper ends of the' lpwer members of the struts by bo-ltsul9, and the lower ends of the tie rods 17 may be fastened to the tubular portion .18l by the bolts 20, as clearly seen in `e roof consists of al plurality of circular rows of segments, the' alternate circular Y are reinforced with respect one to therows of segments being braced or supported from below, the remaining segments bridg- -ing the space between the braced segments and between the perimeter and a braced segment as well as between the roof sheet 4l and a braced segment, as will be presently explained. 'lhe rows are designated 21, 22, 23, 24 and 25.

- )Each segment consists of a seat 26, having a box-shaped girder 27 at one edge anda similar girder 28 at its opposite edge, the' girder 28 being larger than the girder 27 so that when adjacent -segments or roof sheets are brought together, the girder, which consists of a channel, of one roof sheet may receive the opposite edge of the adjacent roof sheet within it, that is, the two lgirders will be nested as shown-in Fig. 3, and packing strips or blocks Will be between the joints so that they can be fastened together to prevent leakage. By nesting the girder at one 'edge of each roof sheet with a similar girder of an adjacent-roof sheet, the circular series or rows of roof sheets are secured together in a. substantially ringshaped unitary structure of considerable strength. y

The second row 22 may have fastened to it 'by the fastening devices 29 which connect the two girders together, a depending girder brace and tie iplate 30, shown as ari angle, the flange 31 of which may be .se-

cured .to the inner face of the small girder by the bolt 29. 'lhere will be a plate 30 depending from each nested set of girders and to each plate 30 will be fastened the upper end of the member 16 of va structure or brace 1H5'. The upper end of the member 16 is shown in lFig. 2 as being flat, as at 32, and fastened to the plate 30 by a bolt 32. The ends of the brace and tie plates other by cross braces shown as Z-beams 33, which have flanges on their ends fastened tol the tieplates v30 by bolts 34 and 35 soI that the second row 22 of segments are all fastened and braced together and supported from' the adjustable sleeve 14 by the struts l5.

The spaces between the inner ends of the 'A segments in' row 22 and the perimeter of the plate 4 are bridged by a. row 21 of seg;- ments which have their inner ends overlapping the outer edge of the roof sheet 4 and which are packed Aby the packing blocks 36, the packing strips' being usedv if desired sothatV there willv be no .leakage Vfrom the roof sheet 4 into the tank.

f 'lhe outer edges of-the segments in the row 21 overlap the roof sheets'in therow 22,v

and, of course, their girders are nested over the girders in the row 22, the overlapping `edges of the roof sheets in row 21 shedding onto the roof sheets .in" row-22.- Y Spacd from the perimeter of the row 22 relates 'is a row 24 of roof sheets constructed substantially like those described in the row 22 and they also have depending brace and tie plates 30 to which the upper ends of the outwardly inclined braces or struts 37 are connected, the lower ends of the struts 37 being supported on the intur-ned flange 38 ofthe circular irons 39 (see Fig. 1).

The outer ends of the roof sheets in row 24 are also supported by the tie and brace rods 40 (see Figa 1). The row 24 terminates short of the wall 1 and the space is bridged by the row 25, whichcorresponds to the row 21 and since 24 is also spaced from the outer end of the row 22, the gapis bridged by the plates 23, which correspond to the row 21. rlherefore, a complete roof is provided, which may be conveniently supported by the struts or braces 15 and 37.

rllhe sleeve 14 isl vertically adjustable on the center pole or standard 3 andbeneath it is a jack sleeve 41, the'upper edge of which -is substantially the diameter-of the sleeve 14 and the lower edge of whichis provided with a circmnferential, outwardly? disposed Harige or foot 42, beneatliwhich the jack aga-inst the weight\ of the roof exerted ,v against the struts which it carries. There- A fore, when the parts are assembled, a jack can be placed under the foot 42 and the prop raised `so that the roof plates will be put under slight tension and will have the proper angle to form the water shed. When the `sleeve 14 is adjusted at the proper height,

it may be secured there by a bolt 43 which extends through the sleeveand through the adjustment openings 44. The bottom of vhe tank may be reinforced by an angle 45. rlhe prop is so constructed and associated with the roof that a substantially umbrella bracing is provided with alternately bracedand bridging roof plates.

46 are tie rods which are transversely arranged toV connect the struts A15 together so as to resist the tendency ofthe struts to spread. Y l* ln lFig. 5 the tying and bracing plate 30' is integral with the girder in contra-distinction to the separate brace plate 30 shown in l'ig. 3.

- In Fig. 6 instead of the brace 30, a channel 30 is bolted in between the sides of the girders to both Vbrace them and serve as a tying-in plate. ln other respects, all of the tying-in plates 30, 30 and 30 are alike.

llt will be seen that the parts can be Vreadily constructed in the factory and sent out into the' field where they may be conveniently assembled .to form a tank of relatively lill) What I claim and desire to secure by Letters Patent is:
